Worth grading — even a PSA 9 beats raw
A PSA 10 Bill Mosienko #27 sells for $5,099 against $20.91 raw: a $5,078 spread, 244× the ungraded price. Even a PSA 9 ($768) clears the raw price after an economy-tier ~$25 fee, so a near-miss still comes out ahead. Centering is the usual reason a clean copy misses the 10 — measure it before you submit.
